一种新的油田开发类比方法——图形类比法

A New Oilfield Development Analog Method-Graphic Analogy

建立了一种新的油田开发相似性判断方法,采用百分比排位对各参数进行归一化,利用多边形形象展示油藏特征,使用叠合面积表征不同油藏间的相似性,采用极短轴表征油田开发的主控因素。该方法原理简单,在数据库中存在大量油田资料时能迅速判断最佳总体相似油田及最佳流动相似、地层相似、流体相似油田,并进行相似性排序。

In this paper, we established a new method to measure the similarity, in which we normalized each pa- rameter by percentage rank to make reservoir characteristics visualized on the polygon. The superimposed area of polygons represents the similarity, the very short axis is the ＂short board＂ of this oilfield. This method is superior in the way of clarity and simplicity in practice when there is a lot of oilfield data. By using this method, the best similar oilfield and other similar aspects, such as in flooding, strata and fluid can be quickly determined.
